Java Program to Check Even and Odd Number.

In this program, we will check if the given number is even or odd. To solve this program we must have a basic understanding of if...else statement in Java.

Algorithm for the Java program to check whether a given number is even or odd:

• Step 1: Start

• Step 2: Read the input number from the user

• Step 3: Check if the input number is even or odd:
• a. If the number is divisible by 2 with no remainder, then it is even
• b. If the number is not divisible by 2 with a remainder of 1, then it is odd

• Step 4: Print the result to the console

• Step 5: End

Java Code Implementation:

import java.util.Scanner;

public class EvenOdd {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("Enter a number: ");
        int num = input.nextInt();
        if (num % 2 == 0) {
            System.out.println(num + " is even");
        } else {
            System.out.println(num + " is odd");
        }
    }
}

Enter a number: 12
12 is even
